A particle at the end of the spring executes S.H.M with a period t_(1), while the corresponding period for another spring is t_(2). If the period of oscillation with two springs in series is .T., then

A particle at the end of the spring executes S.H.M with a period t_(1)

1.	A particle at the end of the spring executes S.H.M with a period t_(1), while the corresponding period for another spring is t_(2). If the period of oscillation with two springs in series is .T., then
Answer» `T=t_(1) =t_(2)` `T^(2) = t_(1)^(2) + t_(2)^(2)` `T^(2) =t_(1)^(-1) + t_(2)^(-1)` `T^(2) =t_(1)^(-2) + t_(2)^(-2)` ANSWER :B
